3. In a large cast iron skillet, heat 1-2 Tbsp neutral oil over high heat. Place salisbury steaks in pan and cook, undisturbed, for about 5 minutes. Once nicely browned on the first side, flip and repeat. Once nicely browned on both sides, remove steaks and set aside. They will still be raw or undercooked in the center at this time and will finish cooking in the gravy.
